Agate is a tool engine to visualize and post-process data from ab-initio codes. It is mainly designed to work with the Abinit DFT code. However, it can perfectly read some VASP files and other commonly used format.

Agate should help you to visualize in a glance any input file to make sure the structure you're simulating is the one you want. You can in some ways modify the structure and save it into a new file with the format you want.

A new Qt GUI is available and is called qAgate.

At the moment the most remarkable functionnalities are for molecular dynamics (MD) simulations and phonon analysis. Agate allows you to extract information of a trajectory to interpret the physics on the system. Several tools are included to make life easier.

Here is a small list of quantities that you can extract with agate from an MD simulation:

• OpenGL capabilities

• Extract images to make a movie

• Concatenate several simulations in one

• PIMD aware : centroid, gyration

• NEB/String methode

• Plot functions :

  • Temperature
  • Pression
  • Volume
  • Lattice parameters
  • Stress tensor
  • Electronic energy (DFT energy)
  • Electronic entropy
  • Kinetic energy
  • Positions
  • Pair Distribution Function
  • Mean Square displacements
  • Positions autocorrelation
  • Velocities autocorrelation
  • Phonon density of states
  • Phonons band structures (if tdep from abinit is available)

  And some phonon related capabilities:

• Visualize indivual or combined mode(s)

  • Extract dominant q vectors
  • Extract indivual mode amplitude
  • Construct your own structure with condensed phonons

Altough the abiout package is available on Windows, MacOS and Linux, only the Linux and MacOS under Hombrew procedures will be presented.

The PPA contains package for all maintained Ubuntu distributions. Simply run

sudo add-apt-repository ppa:piti-diablotin/abiout
sudo apt-get update
sudo apt-get install abiout

and you are done ! Simply execute agate in a terminal.

First you need to install some dependancies. On Ubuntu <= 15.04

sudo apt-get install g++ autotools-dev automake autoconf m4 libtool libncurses5-dev libjpeg8-dev libpng3-dev libnetcdf-dev libcurl3-dev libfreetype6-dev libglfw-dev libeigen3-dev fontconfig ttf-ubuntu-font-family libxml2-dev gnuplot-qt libyaml-cpp-dev libfftw3-dev libssh-dev cxxtest

On Ubuntu >= 16.04 (15.10 not maintained anymore)

sudo apt-get install g++ autotools-dev automake autoconf m4 libtool libncurses5-dev libjpeg8-dev libpng-dev libnetcdf-dev libcurl3-dev libfreetype6-dev libglfw3-dev libeigen3-dev fontconfig ttf-ubuntu-font-family libxml2-dev gnuplot-qt libyaml-cpp-dev libfftw3-dev libssh-dev cxxtest

Then the procedure is the same. Compile abiout with

git clone https://github.com/piti-diablotin/abiout.git
cd abiout
./autogent.sh
mkdir build
cd build
../configure 
make
sudo make install

That's it.

It is exactly the same as for Ubuntu with the following packages (Fedora 22)

sudo su
yum install autoconf automake m4 libjpeg-turbo-devel libpng-devel netcdf-devel libcurl-devel freetype-devel glfw-devel eigen3-devel fontconfig wget unzip libxml2-devel yaml-cpp-devel fftw-devel libssh-devel cxxtest git gcc-c++ gnuplot
git clone https://github.com/piti-diablotin/abiout.git
cd abiout
./autogen.sh
mkdir build
cd build
../configure
make
make install

The procedure has been tested on MacOS 10.14 only and only with Homebrew. Macport should work too.

brew install curl cxxtest eigen fftw freetype git glfw gnuplot libpng libssh libtool libxml2 libyaml netcdf wget yaml-cpp
git clone https://github.com/piti-diablotin/abiout.git
cd abiout
./autogen.sh
mkdir build
cd build
../configure
make
sudo make install

You can also find a precompiled version in the .dmg file contained in the OSX directory.
